Step-Down Controllers

High Power Efficiency
EMI optimization

Superior Performance
Excellent efficiency
and reliability
Design Flexibility
Wide Vin range &
light load

MPS offers a full variety of DC/DC step-down solutions designed to operate directly from a 12V/24V battery or at the point of load. Choose from highly power dense integrated converters with low-Rdson FETs, or flexible controllers with external FETs to easily address high current requirements. Our solutions help address common automotive design challenges like load-dump tolerance, EMI limits, and operation above or below AM band.
